Here is a checklist to keep you and your ride safe and or prevent any mechanical mishaps.
Frame and fork
Check for damaged or bent frame and fork dropouts and rear derailleur hanger.
Make the brake are properly adjusted and in optimal working condition. The brakes should be fully engaged when the brake lever is pulled half way to the handlebar.
Brake levers and lever body should be securely attached. Mechanical brake cables should not be frayed. If using hydraulic brake check any leak around the bleed port, hose port, caliper and lever body.
Check the brake pad wear, there should be at least 2mm between the pad and the rim braking surface and 1mm between brake pad and disc brake rotor.
Check headset, there should be no rocking movement when engaging the front brake and pushing on the handlebar.
Crank-set and bottom bracket
Check that there is no "play" or movement in the bottom bracket or crank-set when holding the crank arms.
The pedals should rotate freely and have no excessive bearing/axle play.
The chain should be lubricated and not slack and or rusty.
Check the gears - shifting should be smooth, precise and almost immediate.
Hubs, axles and quick release skewers
These should be securely tightened.
Wheels and tyres
Wheels should spin freely with no excessive wobbles or buckles. Check for loose spokes by running your hand over the spokes.
Tyres should be inflated within manufacturer’s recommended pressure – values are located on the tyre sidewall. Ensure that tyre thread is not excessively worn and that the tyre has no splits, cracks or holes.
Saddle and seat post
Ensure that the saddle is straight and height is correct, and that the saddle rail clamp and seat post clamp are tightly secured.
Handlebar and stem
Check to see if the handlebar and stem in not loose, and is straight and in line.
Wash your bicycle regularly - first step, lightly apply a water based de-greaser/solvent to the chain-rings, chain, cassette and derailleurs, scrub and let it soak for a few minutes. Next, use warm soapy water and a sponge/brush to wash the bike. Then rinse with clean water taking care not to get water into the the rotational systems - hubs, bottom bracket and headset. Wipe off excess water or let the bicycle dry. When dried apply specific lubricant to chain and where needed apply a lightweight oil to the rest bicycle, its gear mechanism and other moving parts. Avoid use spray lubricants as these can get on the brake disc rotors and contaminating the brake pads.
As with all equipment, you need to take care of your bicycle. It is important to keep it clean as this reduces wear, makes it easier to work on and allows for a better safety check, minimizing the risk of accident/injury due to equipment failure.
That is it, thank you for reading, I hope you found it to be a useful resource.
